The Deeper Link: Blue Light, Cortisol and Your Skin
Prolonged blue light exposure stimulates the hypothalamic-pituitary-adrenal (HPA) axis, leading to elevated cortisol. This stress hormone, when consistently high, contributes to poor sleep, increased skin inflammation, barrier disruption, and collagen breakdown.
Essential oils can directly modulate cortisol via the olfactory and limbic systems, helping reduce inflammation and support the skin’s overnight regeneration cycle. When combined with antioxidant-rich botanical skincare, they create a powerful buffer between you and the overstimulation of modern life.
